Just an update, I still have a few sets of these 36lb injectors on hand. @Blue Wail also mentioned that Racetronix is now selling a 24lb drop-in replacement that looks like a very good piece. If you don't need more flow rate than stock, these are a great option. I don't have any personal experience with them so I can't vouch for how closely they follow the original voltage offsets, short pulse adders or fuel puddling/boiling values, but if he likes them, that's good enough for me.

From this injector rehab company, their take on the stock LT1 injectors:

Coil windings short out internally resulting in a drop (or rise) in resistance. These can sometimes be tricky to detect at home. When the injector is not being pulsed, the injector could ohm out to spec, but once they are energized the problem shows its effects and the resistance will rise or fall. Once this problem occurs, there is nothing that can be done other than to replace the injector. Known for continual leaking. Will be corrected and start leaking again shortly after.
We go so fed up with dealing with these injectors that we dumped 10’s of thousands of cores into our dumpster and vowed to never sell another reman’d core as long as we are in business. One of the biggest pieces of [email protected]#t injectors ever made.
These were commonly found on many GM models from the late 80’s to early 90’s having a grey or black top.
